Reorder registers in other x86_64 assembler files 
This fixes the previous commit which changed the register order in
swapcontext only, which caused setcontext to subtly corrupt the stack.

Merge pull request #10 from fabled/master 
fix x86_64 register order for swapcontext
 2018-07-19 00:33:12 -05:00
Timo Teräs 790ed28aff fix x86_64 register order for swapcontext 
rbp and rsi were reversed causing argument passing to fail since
rsi is used to pass 2nd argument.

fixes #9
